Cisco 400-007 Exam With Confidence Using Practice Dumps

Inbound traffic engineering is best controlled by manipulating how external ASes view your routes.

AS path prepending on the 91.7.0.0/16 prefix towards AS 200 makes AS 500 prefer the less-prepended path through AS 100.

This allows granular inbound control for that specific prefix while leaving the rest of the traffic unchanged.

Why other options are incorrect:

B: Extended community is not used for direct inbound path manipulation.

C: Local preference affects outbound traffic, not inbound path selection by remote ASes.

D: MED is only compared between the same AS; it won't affect AS 500's choice.

When an ACL is applied inbound on the Internet gateway interface facing the internal (trusted) network, the source IP address seen in the ACL will be the address after NAT translation has been applied to outbound traffic. This is called the inside global address:

Inside global = Public IP assigned by NAT to inside traffic for external use.

Inside local = Internal IP address prior to NAT.

Why other options are incorrect:

B, D: Outside addresses refer to external devices, not internal traffic.

C: Inside local is seen before NAT, not after.

The IoT ecosystem continues to evolve around industry-wide agreements on protocols, frameworks, security, interoperability, and standards:

D: Multiple IoT consortia (such as Industrial Internet Consortium, Open Connectivity Foundation, etc.) are still developing open frameworks and interoperability models.

E: IoT standards for security, data privacy, management, and protocol interoperability are still maturing as the market rapidly evolves.

Why other options are incorrect:

A: Wi-Fi protocols (such as 802.11ax) are already mature and standardized for IoT.

B: Regulatory domains (frequency allocations, power levels) are already well-established.

C: Low-energy Bluetooth sensors are already standardized and widely implemented.
